AH oil cooler ducts

[HealeyPassion]

This undoubtedly has a limited audience, but for those interested and unstable like me :crazy: .... here is my project paper on AH works rally/Sebring oil cooler ducts.

Very tasty appearance. And gutsy; you could have really blown it!

 

[Randy Forbes]

That's nice, I noticed the rolled edges when looking at your paper on wet-sanding and polishing the paint, good job!

I took a somewhat less technical approach, using a 3" conduit K/O punch to get radiused ends, simply cutting out the material left in between.

I fabicated a stainless steel duct to direct air into the cooler matrix, attaching it to the shroud with aircraft "cherry" rivets sandwiching a #10 stainless steel screen between the two (and I have a particular fondness for Pinin Farina's similar use of exposed rivets on the Ferrari 375 Mille Miglia; see: https://www.rfdm.com/gallery/album116 ).

Another stainless duct carries the air exhausted through the oil cooler out and under the radiator.

Hello HealeyPassion,

Another fine project update, well written and documented. I love looking at your website.

Hello Randy Forbes,

I like what you have done even though I would have done it differently. I like the duct from the opening to the oil cooler matrix. I would have used aluminum alloy rather than stainless because of dissimilar metals. Also the same for the rivets. I would have used solid rivets. Yes a little more difficult to install but that's me. The "cherry" rivets will come loose eventually as they don't like vibration.

HealeyPassion was lucky in that his shroud was off the car to do this.

Best regards,

bundyrum.

Randy, I really like how you handled the ducting behind the shroud....very slick!

Cheers,
Steve

Thank you, no point in putting that hot air into the (water) radiator :wink:

Bundy, since when do Healeys vibrate?

One other good step -I follow you on the way
also my car should be with Sebring Ducts
and Oil Cooler- the same model of Randy-
with thermostatic control on the spin Filter
also Lin Rose have made this mod but with different size - if I remember well (6"x2"3/4)
Steve the Oil cooler can be useful for your powerful
car- the addition can be easy at your build status

[HealeyPassion]

Andrea, interesting that you mention Lin's ducts. Yes, Lin's are a bit different size but the concept is similar... yes, he did his first and was part of the inspiration for mine.

I have an oil temperature gauge so I'll know if I need to add an oil cooler....given how I plan to use the car I don't think I'll need it. I have one screaming fast car that I track so I plan to use this for touring and romps in the mountains.

Cheers,
Steve

Hello RandyForbes,

From the day they were born.

For those of you whose cars don't vibrate I don't need to know.

Steve,

Beautiful work as always. I probably should have incorporated these and the side vents to get some heat out of the engine room, but my bodywork and paint are all done, so probably too late. Your stick on patterns gave me an idea, though. Maybe I can get some fake vents made out of that vinyl material the NASCAR racers use to make headlights and grilles. At least I can look the part.

 

[BUNDYRUM]

Hello HealeyRick,

That's a great idea having fake vents, would save a lot of time and effort.

But seriously, your car isn't all together yet so I'd say this is the perfect time to do it. With a little bit of care you shouldn't need to do too much paint touch up.

You have already shown us the excellent standards you work to so why not?.

Best regards,

bundyrum.

 

[HealeyRick]

Bundyrum,

Much as I'd like to take an undeserved compliment regarding my work standards from an aviation metalworker, my late Mom and Dad (who BOTH built engines at Pratt & Whitney during WWII) would come back to haunt me if I did. I'm willing to try anything once and have made a fair amount of mistakes that I've learned from. So by now, I have a pretty good idea what I can and can't do and leave the stuff I'm not good at to the pros. Cutting up sheetmetal and trying to paint match Healey blue are way above my skill set. I have thought a bit about ways to install fender louvers without welding. Seems to me with today's bonding materials there should be away to run a flange around the vents and bond the flange to the inside of the fender. The scary part would be cutting into the fender without damaging the paint.

Cheers

Well Rick, if you don't want to cut the shroud, maybe you could do something similar to my approach. I put the cooler between the frame rails and built a scoop to both direct the air and protect from road debris. Full thread is HERE

Here's another version

Now look hard at the middle photo, consider the headlights as eyes, the grille as the nose and the oil cooler duct as the mouth.

Yes Folks, I think we have an extra from Pixars 'Cars' animation.

 

[HealeyPassion]

Rick,
The issue with the side fender vents is that you are joining a flat surface (vents) to a curved surface (fender). Todays bonding agents would probably handle the job, but getting the contours to look good without body work would be the issue. It was clearly above my skill set....so my trusty body guy handled mine.

Cheers,
Steve

Hello Frankenhealey,

I just managed to get onto the V8 forum only to discover you own the late Greg Greathouse's BN1.

I first met Greg in 1982 then from time to time at various vintage race events here in the San Francisco bay area.

It's nice to see what you have done to the car and undoubtedly maintained the spirit of the way Greg originally built the car.

Best regards,

bundyrum.

Hadn't thought of that issue, Steve. Thanks. Guess it's back to the pasties for me.
